ALINING DEVICE FOR COIICEETE-FORMS.

Specification of Letters Patent.

Patented Nov. 21, 1916.

Application filed July 7, 1916. Serial No. 107,910;

To all whom it may. concern:

Be it known that I, WILLIAM B. JONES, a citizen of the United States, residing at Streator, in the county of La Salle and State of Illinois, have invented certain new and useful Improvements in Alining Devices for Concrete-Forms, of which the following is a specification.

My invention relates to inventions in alining devices for concrete forms, and refers more particularly to that class of apparatus of which the subject matter of the United States patent to HeltzelNo. 1,141,057, issued May 25, 1915, is an example.

Among the salient objects of the invention are, to provide a device of the class described in which the position of the concrete form may be accurately and rapidly determined; to provide a construction which permits of vertical and horizontal adjustment of the form in any position within the range of movement of the adjusting devices; to provide a construction so organized that the top and bottom of the formmay be moved relatively to each other without changing the position of the form as a whole; to provide an improved construction of form utilized for the construction of curbs or analogous structures of concrete; and, in general, to provide improved apparatus of the charac ter referred to.

In the drawings which illustrate the application of my improvements to a form for laying concrete curbs, Figure 1 is a side elevation of a stake provided with alining device, the end of'the curbform being indicated in section; Fig. 2 is an end elevation of the parts shown in Fig. 1; Fig. 3'is a perspective view of the front and back members of the curb form and the dividing plate therefor; Fig. 4 is a section taken on the line H of Fig. 1; Fig. 5 is a perspective view of one of the dividing plates; Fig. 6 is an elevation of a modification of the device shown in Fig. 1; Fig. 'Tis a side view of the device shown in Fig. 6; and Fig. 8 is a perspective view of a modification of the curb form construction shown in Fig. 3.

Referring to the drawings, 10 represents the front plate of the curb form and 11 the back plate, these plates being constructed with substantial turned. over flanges, as shown at. 12v and 13, in order to stifien the plates, which are preferably made of relatively thinmetal in order. to save expense and reduce weight; In laying concrete curbs it is customary to divide the curb into sections five or six feet long by means of dividers or spacing plates, as shown at 14, said dividing plates being in my improved construction utilized to support the back plate 11 and secure same in proper position relative tothe front plate 10.

In Figs. 1 and 2, 15 is an ordinary stake, which in the present case is a length of wooden scantling, the end of which is pointed, as shown at 16 so that it may be driven into the ground. 7

It is of course understood that a stake made of other material, such as metal, may be employed ifdesired. Secured to the side of said stake by means of a pair of bolts 17 and 18 passing through the stake is a flat plate 19 which is spaced apart from the side of the'stake by means of a pair of fiat square, washers 20 and 21 through which the bolts pass. The heads of the bolts 17 and 18 are preferably made flush with the front of the plate 19 by countersinking the latter, as indicated at 22 and 23.

The plate 19 is preferably made rather wider than the width of the stake 15, and along the side edges of the plate 19 there are secured a pair of guide pieces 24 and 25, the inner edges of which are preferably grooved or recessed to accommodate a flat plate 26 which is capable of vertical sliding movement in said guides. In order to permit the slide plate 26 to be adjustably secured in any vertical position on the foundation plate 19, the latter is slotted, as shown at 27, in order to accommodate the squarenecl: of the bolt 28, the head of which is located behind said foundation plate 19 and the screw part of which projects through a hole in the slide plate 26 and is equipped with a wing nut 29. It will be readily understood that by loosening the wing nut 29, the plate 26 is permitted to slide up and down in the guides, while tightening of the nut 29 will prevent further such sliding movement.

Mounted transversely across the front of the sliding plate 26 are a pair of transverse upper guides 30 and 81 and a lower pair of similar guides 32 and 33, the upper pair of guides accommodating a supportingbar 34, the lower pair of guides accommodating a sliding positioning bar 85. A pair of thumb screws 36 and 37 enable the bars 8 1* and 35 to be 'adjusted 'in any position in said trans verse guides.

Referring to Fig. 1, it will be observed that the end of the bar 34 has an upward projection in which is cut a slot 38 slightly wider than the thickness of the metal of the down turned portion 39 of the flange 12 of the front plate. The lower adjusting bar is provided with an upwardly projecting tongue or lug 40 which is of suitable cross section to enter an aperture 41 in the lower flange 13 of the front plate 10. The front plate 10 is thus supported and positively positioned by means of the slide bars 34 and 35.

The dividing plate 14 by which the back plate 11 is separated from the front plate 10 is illustrated in Fig. 5, and as shown in said figure, it is constructed with an outer projecting part 42 connected to the main area of the plate by means of a neck part 43 which enters a slot 44 in the top of the front plate, said front plate also being apertured at 45 as to its top flange 12 in order to permit the insertion of the tongue piece 42. The tongue piece 42 and the main area of the dividing plate are separated by a slot 46 which is of suflicient width to accommodate the metal of the front plate 10 below the slot 44. The lower end 47 of the tongue piece 42 is prevented from rocking sidewise by means of a pair of flat positioning blocks 48 and 49 spaced apart the proper distance to fit on either side of said tongue piece 47.

The construction just described maintains the spacing plate 14 in an upright position all the time but permits the spacing plate to be withdrawn vertically whenever it is desired to dismantle the form.

Further describing the attachment between the back plate 11 and the front plate 10, 50 is an integral lug on the spacing plate projecting through a vertical slot in the side ofthe back plate 11, the latter being prevented from moving outwardly away from the front plate by means of a flat wedge 51 which is fitted in a small slot 52 punched in the lug 50. It is obvious that the lug 50 will support the back plate 11 in proper position while the key or wedge 51 will prevent the two plates from becoming separated.

Describing the means for splicing or j ointing together adjacent sections of the front and back plates, 101 re resents a flat channel shaped strap mem er of metal fitting within the channel of the front plate and riveted as at 102 to the end of the front plate 10 in such position that the succeeding front plate section 103 will slide or telescope over the projecting end of said junction strap 101. The sections of the back plate 11 are spliced or jointed together in the same manner.

With my improved apparatus the curb forms may be set in position with a minimum of expense or inconvenience. The

stakes 15 are first driven into the ground in as nearly correct position as possible. The curb plate 10 is then hung or supported on the ends of the bars 34 and 35 and the slide plate 26. is raised or lowered in the right position to bring the top of the form to the desired horizontal level. The upper bar 34 is then slid inwardly or outwardly in order to bring the top of the form into proper alinem-ent, and the lower bar 35 may then be adjusted inwardly or outwardly in order to correct any possible twisting or inclination of the form. It will be readily understood end on the bolt 18, and in the top of the plate there is punched an arcuate slot 54 to accommodate the bolt 17 and allow for swinging movements of the foundation plate 53 around the bolt 18 as its center. With this construction it is unnecessary to make the upper and lower form supports independently adjustable of each other. In this case the vertically slidable plate 55, which slides up and down between the guides 24 and 25, is equipped with a single pair of transverse guides 56 and 57 between which slides transversely a cross plate 58. The outer ends of the cross plate 58 support the form in the same manner as the bars 34 and 35 in the preferred form shown in Fig. 1. A slot 59 punched in the plate 58 accomm-odates a bolt 60 having a wing nut 61 for fixing the transverse position of the cross plate. This modified construction is in some respects-somewhat cheaper to manufacture than the preferred form heretofore described.

In Fig. 8, which shows a modified form of joint between the adjacent lengths of the form members, 104 represents the junction strap pivoted to the end of the front plate 10 and projecting the same distance from the end thereof so as to slide or telescope in the end of the adjacent front plate section 103. The joint connection is in this case improved by punching an ear 105 out of the top and bottom of the front plate 103 and folding same back upon themselves as shown, in order to embrace the ends of the junction piece 104. Such construction possesses some advantages over that shown in Fig. 3.

The structural details herein described are merely illustrative of a single application of my invention, the scope of which must be determined by reference to the appended claims.
